Hello

I need help with question 4 d and e

[lone lodge]

so y=-2x-1?

[neon pilot]

Yes

[lone lodge]

to find the x intercept plug in y = 0
and for the y intercept plug in x = 0

[neon pilot]

Ok

Actually can we work out 4) e)

[lone lodge]

alr

[neon pilot]

2y = x - 3

[lone lodge]

2(0) = x - 3

0 = x - 3
3 = x

for the y intercept

[neon pilot]

Ok 👍

Now y-int

[lone lodge]

i meant x intercept

for the y intercept

2y = (0) - 3

2y = -3
y = -3/2

[neon pilot]

Ok makes sense

Thanks 🙏

[lone lodge]

anything else?

[neon pilot]

One sec

I don’t understand this at all

Question 10) a) and b)

[lone lodge]

for a, when x = 0, y = 4

[neon pilot]

Yep

[lone lodge]

and when x = 4, y = 0

[neon pilot]

I don’t get what the question is asking me to do

[lone lodge]

ax+b(0)=d

a(4)=d

[lone lodge]

because of this, d = 4

4a = 4
a = 1

[neon pilot]

what does the a represent

[lone lodge]

a(0)+4b=4

b=1 aswell

[neon pilot]

And what does the b represent

[lone lodge]

b and a affect the slope

[neon pilot]

How would I write the answer in my book

[lone lodge]

what do you need to write?

Answer for 10a and b

Question 10a and b

[lone lodge]

[(y at x = 0)/(x at y = 0)]x + [1]y = (y at x = 0)
